Underwater Backscattering Strengths of Arctic Pack Ice

The Journal of the Acoustical Society of America, 1964
The backscattering strengths under Arctic sea ice for octave bands between 12 cps and 4 kc/sec were measured, using explosive sound sources. The measurements were made from a camp established in April 1962 on broken and pressure-packed one-year ice over the Canada Deep.

Observations of internal gravity waves under the Arctic pack ice

Journal of Geophysical Research: Oceans, 1987
Internal gravity waves measured under the Arctic pack ice were strikingly different from measurements at lower latitudes. The total wave energy, integrated over the internal wave frequency band, was lower by a factor of 0.03–0.07, and the spectral slope at high frequency was nearly −1 in contrast to the − 2 observed at lower latitudes.

Winter Sightings of Marine Mammals in Arctic Pack Ice

ARCTIC, 1987
There is limited information about the winter distribution of some arctic marine mammals. In February-March 1976 six species of marine mammals were sighted in the pack ice of Baffin Bay and Davis Strait. Hooded seals were sighted along the ice edge in February, but in late March adults with pups were seen.

Seasonal dynamics of sub-ice fauna below pack ice in the Arctic (Fram Strait)

Deep Sea Research Part I: Oceanographic Research Papers, 2006
Abstract Pronounced seasonality is a characteristic feature of polar ecosystems, but seasonal studies in the high-Arctic pack-ice zone are still scarce because of logistical constraints. During six expeditions (1994–2003) to the Fram Strait area between Greenland and Svalbard in winter, spring, early summer, late summer and autumn, the sub-ice ...

The Effect of Tensile Strength in the Arctic Ice Pack

2001
The ice pack covering northern seas is composed of an aggregate of thick ridged and rafted ice, undeformed ice, and open water. Existing ice-ocean models of the Arctic ice pack are large-scale continuum models that use a plastic yield surface to characterize the constitutive behavior of the pack. An alternative approach, which captures far more detail,

Temporal Variability of the Energy Balance of Thick Arctic Pack Ice

Journal of Climate, 1998
Abstract The temporal variability of the six terms of the energy balance equation for a slab of ice 3 m thick is calculated based on 45 yr of surface meteorological observations from the drifting ice stations of the former Soviet Union. The equation includes net radiation, sensible heat flux, latent heat flux, bottom heat flux, heat storage, and energy

Studies of the Solar and Terrestrial Radiation Fluxes over Arctic Pack Ice

1970
Abstract : The report describes some measurements carried out during 1972 AIDJEX that have not been accounted for in earlier reports under this contract. Determinations of the turbidity coefficient gave a mean value of 0-078, indicating that the dust scattering is considerable in the Arctic atmosphere.
